Unfortunately, it stopped working for some reason. :-( Probably, I need to reboot. Anyway the change was like this: @@ -384,6 +390,8 @@ req.wIndex[1] = 0; USETW(req.wLength, 0); + pause("DLY", hz / 10); + err = usb2_do_request_flags (sc->sc_udev, &Giant, &req, NULL, 0, NULL, 1000); What kind of debugging info are you interested in? Should I enable hw.usb2.ubsa.debug?
